About Forecasting Air Pollution in the Construction of Highways

[摘要] The article considers the main types of environmental pollution in the construction of highways. First of all, they are the formation of dust (during the movement of transport, during the transportation of building materials, as well as in a number of technological operations) and the noise effect created by operating machinery. All the factors affecting the ecological situation in the residential area of road construction have been analyzed. The harmful content and elemental composition of fine dust (PM10 and PM2.5) during the construction period was investigated. The main sources of the release of pollutants into the atmosphere during the construction and repair of the motor road were considered namely: construction machinery; dust particles from the surface of the roadbed, sections of the pavement device, storage areas for loose building materials, etc. It is shown that the PM10 and PM2.5 dust concentrations can be considered as random quantities, and approaches to their prediction are also proposed.
